Rated 3.9 out of 5 by 48 reviewers.
Rated 5.0 out of 5.0 by Bright lights I installed eight of these in my 16'x20' shop. They are bright and provide even light for using woodworking tools. February 10, 2015
Rated 5.0 out of 5.0 by Daylighting Good I have installed these in my shop and am very satisfied. I chose this bulb due to the high color temperature. Downside is that they are more expensive than other choices. After approximately 6 months, I have not had any problems. The previous post indicated that they might burn out fast. I had this problem with a different flourescent tube bulb, but only after I had put it on a motion sensor. I discovered that the life of flourescent bulb was greatly shortened by frequent cycling of the ight on and off. December 9, 2012
Rated 5.0 out of 5.0 by Perfect Application This 10-pack was exactly what I needed to complete the shop lighting project for my small barn. I was installing 5 overhead shop lights requiring 2 bulbs per fixture and decided that instead of using standard light level tubes I would like a brighter light as the interior has 288 square feet on the ground floor and a loft area of 190 square feet. These bulbs definitely did the job well and at a price point that was very reasonable. June 24, 2014
Rated 5.0 out of 5.0 by Great Fluorescent Bulb, Too bad my local Home Depot no longer carrys these. This is a high quality bright fluorscent bulb. It is hard to find a bright daylight bulb in a multi-pack. The quality is high, and the lights achieve full brightness in a short time, even when it is cold. I have several lights in my new garage that I used these bulbs in, and I am very pleased with the results. .......... With that being said, I don't understand why Home Depot no longer carrys these in my local store. The 1st 2 cases of 10 I bought in my local store. The last case of 10 I had to order online. I don't know what Home Depots logic is, or if there is any logic to this. January 27, 2015
Rated 1.0 out of 5.0 by Short life After going through two boxes(10 ea) I've stopped using Phillips Fluorescent bulbs. They failed repeatedly after only a few months. After switching to Sylvania Fluorescent bulbs from Lowes I have not had one over a year. February 25, 2015
Rated 4.0 out of 5.0 by good price The bulbs were really bright , but one of the ten bulbs did not work . March 10, 2015
Rated 5.0 out of 5.0 by Great bulbs, but make sure you use proper T8 fixtures/ballast for these bulbs I really like these bulbs and have had excellent life from them, with great color. It's like I'm working in a new shop. I'm guessing the reviewers who have had very short lifespans with these bulbs are using them in old T12 fixtures with T12 magnetic ballast. If you do these bulbs will light, but you will significantly shorten the bulb and ballast life as well as chew up more energy. The bulbs may fit in old T12 fixtures, but don't use them like that. These bulbs are to only be used in the fixtures they were designed for, T8 fixtures with T8 ballast. January 7, 2014
Rated 4.0 out of 5.0 by Performs as expected Good lighting. It's white. So, it looks a bit different than the others I have that were not replaced. If this is something that would bug you, make sure you're buying the exact same type of light. April 8, 2014
